 Using the technology of the internationally recognized good source of Industrial Science and Technology Co., Ltd. R & D MD24-type water bath nitrogen through nitrogen gas blown into the heating of the sample surface to concentrate the sample, the analysis time, to meet the need for rapid detection. This method is time-saving, simple operation, easy control and low cost. 
 The instrument includes a base and bracket device, the sample holder and gas distribution systems. Test tube test tube with a spring clip support plate to a fixed location. Each sample are numbered; gas through the meter to reach the gas distribution system, a flexible guide tube of the gas into each position of the valve and stainless steel needle and blowing the gas to the sample surface, so that the solvent to evaporate quickly. Each airway according to the number of test tube size and solvent independent movements to the right height. 
 The round stainless steel water bath temperature can be adjusted and can be controlled accurately maintain a constant water temperature in the range of ~ 99 ℃ room temperature. 

 Features 
 (1) test tube (diameter 10 to 29mm), flask, centrifuge tubes, the sample capacity of 1 ~ 50ml 
 (2) the sample median of 24 spring tube clip sample holder fixed positioning, each sample has a digital ID 
 Free movements of the needle valve tube, needle valve to control every grade nitrogen flow and switch 
 Circular structure, rotating freely, the convenience sample holder out of the water bath, easy to operate 
 Standard gas needle length: 150mm 
 6. Round constant temperature water bath, temperature display, water temperature: room temperature ~ 99 ℃ 
 All components can be resistant to organic solvents. 
 Concentrated toxic solvents, the entire system can be placed in a fume hood
